The second was the Quichua Pygmy marmosets are not included in any of the IUCN categories in the Red Data Book of Ecuadorian mam- mals; they are listed only in the CITES Appendix II (Tirira, 2001). However, based on the evidence we have gathered during almost seven years of research, we suggest that the status of this species needs to be revised. Indeed, the populations we have studied in northeastern Ecuador have been severely affected by live capture, noise pollution and habitat destruction (de la Torre et al., 2000; Yépez et al., 2003). These factors are related to the development of the petroleum industry, the continuous increase of human populations due to high reproductive and migra- tion rates, and the cultural loss which native communities are experiencing due to their rapid insertion into West- ern cultures (Ministerio del Ambiente et al., 2001). All these factors have altered the equilibrium of natural ecosys- tems and are negatively affecting the populations of pygmy marmosets. Live capture of pygmy marmosets, in particular, is a common practice of children and adults of many indig- enous communities. They are also eaten in some areas, or killed for target practice in others. We believe that these problems could be mitigated with a program of environ- mental education. We began such a program this year, directed to the children of the communities that live close to some of the pygmy marmoset populations we studied. Yépez Pablo Credit: Figure 1.

Lecythidoideae is limited to the Neotropics and is the only naturally occurring subfamily of Le- cythidaceae in the New World. A subset of genera with zygomorphic flowers—Bertholletia, Corythophora, Eschweilera and Lecythis—comprises a group of about 125 species called the Bertholletia clade. A previous study based on plastid ndhF and trnL-F genes supported the monophyly of Corythophora but suggested that Eschweilera and Lecythis are not mono- phyletic. Using this study as a baseline, we sampled more taxa and sequenced more loci to address the taxonomic problems of the ambiguous genera and to determine relationships within the Bertholletia clade. Our results support the monophyly of the Bertholletia clade as previously circumscribed. In addition, Corythophora is monophyletic, and the two accessions of Bertholletia excelsa come out together on the tree. Results of the simultaneous analysis do not support the monophyly of Lecythis or Eschweilera.

    Acta bot. bras. 4(1): 1990 4S DIVERSIFICAÇÃO E CONSERVAÇÃO DAS LECYTHIDACEAE NEOTROPICAIS ScottMori 1 RESUMO - As Lecythidaceae (família da castanha-do-Pará) são árvores tro­ picais de planície que atingiram sua maior diversidade em espécies nos neotró• picos. No Novo Mundo, a família está mais diversificada em habitats de terra firme na Amazônia e nas Guianas. Pouco mais de 50% de todas as espécies neo­ tropicais de Lecythidaceae são encontradas na Amazônia, sendo a Amazônia cen­ tral especialmente rica em espécies. Uma única área de ~OO hectares, 90 Km ao norte de Manaus apresenta 38 espécies diferentes de Lecythidaceae. Além disso, um grande número de espécies de Lecythidaceae têm o centro de distribuição na província florística das Guianas. As espécies de Lecythidaceae com flores actino­ mórficas são mais numerosas no noroeste da América do Sul, enquanto que as es­ pécies com flores zigomórfas predominam da Amazônia central até as Guianas. As matas costeiras do Equador e da Colômbia até o Panamá abrigam sete espécies de Lecythidaceae ameaçadas de extinção e nove das 15 espécies de Lecythidaceae que ocorrem nas matas do leste do Brasil extra-amazônico são endêmicas. Estas matas costeiras do Pacífico e do leste brasileiro devem receber alta prioridade quanto à conservação das Lecythidaceae, porque são nestas matas que o alto grau de endemismo coincide com extremo destamatamento. Palavras-chave: Lecythidaceae, neotropical, padrão de distribuição geográfica. ABSTRACT - Lecythidaceae (Brazil nut family) are lowland, tropical trees which have reached their greatest species diversity in the Neotropics. In the New World, the family . is most diverse in terra firme habitats of Amazonia and the Guianas.

The phylogenetic relationships of the genera of Lecythidaceae and representatives of Scyto­ petalaceae were assessed using cladistic analysis of both molecular (rbcL and trnL se­ quences) and morphological data. The results show that the pantropical family Lecythida­ ceae is paraphyletic. Support was found for the monophyly of three of the four subfamilies: Lecythidoideae, Planchonioideae, and Foetidioideae. The fourth subfamily, Napoleonaeol­ deae, was found to be paraphyletic, with members of the Scytopetalaceae being nested within it forming a strong clade with Asteranthos. Both families share a number of mor­ phological features, including several distinct characters such as cortical bundles in the stem.

  • Revisiting the Hyperdominance of Neotropical Tree Species Under A
    www.nature.com/scientificreports OPEN Revisiting the hyperdominance of Neotropical tree species under a taxonomic, functional and evolutionary perspective Gabriel Damasco1,2*, Christopher Baraloto3, Alberto Vicentini4, Douglas C. Daly5, Bruce G. Baldwin1 & Paul V. A. Fine1 Recent studies have leveraged large datasets from plot-inventory networks to report a phenomenon of hyperdominance in Amazonian tree communities, concluding that few species are common and many are rare. However, taxonomic hypotheses may not be consistent across these large plot networks, potentially masking cryptic diversity and threatened rare taxa. In the current study, we have reviewed one of the most abundant putatively hyperdominant taxa, Protium heptaphyllum (Aubl.) Marchand (Burseraceae), long considered to be a taxonomically difcult species complex. Using morphological, genomic, and functional data, we present evidence that P. heptaphyllum sensu lato may represent eight separately evolving lineages, each warranting species status. Most of these lineages are geographically restricted, and few if any of them could be considered hyperdominant on their own. In addition, functional trait data are consistent with the hypothesis that trees from each lineage are adapted to distinct soil and climate conditions. Moreover, some of the newly discovered species are rare, with habitats currently experiencing rapid deforestation. We highlight an urgent need to improve sampling and methods for species discovery in order to avoid oversimplifed assumptions regarding diversity and rarity in the tropics and the implications for ecosystem functioning and conservation. Accurately defning species and their distributions is critical to understanding the processes responsible for both the generation and the maintenance of biodiversity. Te increasing availability and analysis of species distribution data through forest inventory networks (e.g., GBIF, ATDN, RAINFOR, PPBio, DRYFLOR, 2ndFOR) has resulted in important conclusions about species diversity (e.g.,1–3) and related ecosystem processes (e.g.,4–6).

  • Diversification History of Neotropical Lecythidaceae, an Ecologically
    Chapter 29 Diversification History of Neotropical Lecythidaceae, an Ecologically Dominant Tree Family of Amazon Rain Forest Oscar M. Vargas and Christopher W. Dick Abstract The Neotropical subfamily of Lecythidaceae (Lecythidoideae) is a clade of 10 genera with an estimated number of 232 species. Lecythidaceae is the third most abundant family of trees in Amazon forests, and its most diverse genus, Eschweilera (ca. 100 species) is the most abundant genus of Amazon trees. In this chapter we explore the diversification history of the Lecythidoideae through space and time in the Neotropics. We inferred a time-calibrated phylogeny of 118 species, which we used to reconstruct the biogeographic origins of Lecythidoideae and its main clades. To test for significant changes of speciation rates in the subfamily, we performed a diversification analysis. Our analysis dated the crown clade of Lecythidoideae at 46 Ma (95% CI ¼ 36.5–55.9 Ma) and the stem age at 62.7 Ma (95% CI ¼ 56.7–68.9 Ma), suggesting dispersal from the paleotropics long after the Gondwana breakup. Most major crown clades in the Lecythidoideae (Grias, Gustavia, Eschweilera, Couroupita, Couratari, and all Lecythis and Eschweilera subclades) differentiated during the Miocene (ca. 5.3–23 Ma). The Guayana floristic region (Guiana Shield + north-central Amazon) is the inferred ancestral range for 8 out of the 18 Lecythidoideae clades (129 species, ~55%), highlighting the region’s evolutionary importance, especially for the species-rich Bertholletia clade, which includes the genera Eschweilera, Lecythis, Corythophora and Bertholletia. Our results indicate that the Bertholletia clade colonized the Trans-Andean region at least three times in the last 10 Ma.
